This would result in a poor survival rate for all the seeds.Instead, when a seed hooks on to a passing animal using its spines, it can travel a great distance – hopefully falling off somewhere more suitable for it …

Lesser Burdock. Sea Holly. Many plants produce fruits or individual seeds covered in hooks or spines which attach the seed to the animals’s fur or feathers – or, in the case of humans, to our clothes or bags. The seeds are then carried a sufficient distance from the parent plant to give them space to grow.
Seeds that are dispersed externally by animals use hooks or spines to cling onto the fur of animals as they brush past the plant. These then drop off later after the animal has moved on. Examples include burdock. Internal animal dispersal. Seeds that are dispersed internally by animals use a fruit to entice the animal to eat the seeds.
Epizoochorous dispersal by barbs, hooks, and spines in a lowland moist forest in central French Guiana. Brittonia 50: 165-173. 1998.–An analysis of the flowering plant flora of a lowland moist forest in central French Guiana reveals 25 species with adaptations for epizoochorous dispersal by barbs, hooks, or spines (stick-tights).
Epizoochorous dispersal by barbs, hooks, and spines seeds because of the reward provided by edible parts of the fruits or seeds. The great- er diversity of tropical plants and animals barbs, hooks, and spines, the dispersal unit contains a single seed, either from the onset or by the eventual break-up of multiseeded
The seeds of fleshy fruits such as those of cherries and blueberries are tasty to many animals and are well adapted for passing through an animal gut intact. Others have hooks, spines, hairs, or sticky surfaces and adhere to the feathers or fur of animals that brush against them; thus, they are eventually transported to new locations.
Flowering Plants with Spiny Seed Pods. By Carolyn Csanyi. For seed collectors, spiny seed pods are literally a pain. Picking the pods can be a challenge, and then opening them to retrieve seeds can be unpleasant. The spines do serve a purpose in the plant world because the sharp projections help deter hungry herbivores from accessing the seeds.
Spines. Spines are modified leaves, stipules, or parts of leaves, such as extensions of leaf veins. Some authors prefer not to distinguish spines from thorns because, like thorns, and unlike prickles, they commonly contain vascular tissue. Spines are variously described as petiolar spines …

Awns are sharp. structures produced on grasses and small grains. These structures are found in seed head region or “glumes”. of plants—often labeled the “beard.”. Barley, rice, wheat and other grains have such structures. The following plants have spines or thorns on some portion of the plant.
It has long spines that look like fish hooks, which is how it got its name. This cactus, like others, survives through photosynthesis. In the early summer, red and purple flowers begin to grow from the side of the cactus and can grow to be as large as the cactus itself! The fish hook cactus reproduces by seed.
Seed dispersal is the movement or transport of seeds away from the parent plant. The small hooks on the surface of a bur enable attachment to animal fur for dispersion. including adhesive mucus, and a variety of hooks, spines and barbs.
